To hit the point home, was was wondering if you could tell me if I am setting up the appropriate functions correctly for a problem: A butcher throws a cut of beef on spring scales which oscillates about the equilibrium position with a period of T = 0.500 s. The amplitude of the vibration is...

Homework Statement I was wanting to get some clarification on some of the simple harmonic motion equations. So, say for example there is a box of mass "m" undergoing simple harmonic motion attached to a spring of spring constant K on a horizontal surface. To find where the box is, as a...

Homework Statement Hello, I'm looking for some help on how to perform some lab calculations. We recently did a lab on the Preparation of Geometric Isomers. We were preparing the Cis and Trans isomers of butenedioic acid, i.e Fumaric and Maleic Acid. The Maleic acid was done by reacting...

I'm trying to understand how to draw MO diagram for molecules such as CO, HF, and NO. I am finding so much conflicting information on how to order the σ and pi boxes in the diagram. Now, I know that the more electronegative atom's orbitals are going to be lower in energy than the less...

Homework Statement Hi. I am currently doing a lab where I need to convert mm Hg to atmospheres. When I try to use an online converter to do this, it gives two options for atmospheres, technical and standard. Which would be the best to use for a laboratory calculation...

So can you just treat each unit vector separately and integrate and evaluate each individually, then combine them all to find the displacement vector? Thanks!

Homework Statement Say for example, a particles velocity was given by the following equation: \vec{V}(t) = (2t2-4t3)\hat{i} - (6t +3)\hat{j} + 6\hat{k} If I wanted to find the displacement of the particle between t=1s and t=3s, could I just integrate like this? \int \vec{V}= (2t3/3...

Say you use dot product and get 109 degrees, and using cross product you get 71 or 109. It would have to be 109 right?

Thing is, I never do it that way really. I guess since arccosine is defined between 0,pi it will have to give the unique and only possible angle? Thanks :)

Homework Statement I have been doing dot and cross product recently. I get how to calculate everything; however, I am confused about which angle to use when asked to find the angle between two vectors. When you use the cross product, you always end up with 2 answers, for example 120° and...

Homework Statement This isn't a homework question, but I will try and follow the template. I am confused about the relationship between the absorbtion and emission spectrums for hydrogen. I was taught that in the balmer series for hydrogen, when an electron moves from the n=1 level to...

Homework Statement I am currently reviewing the physics of 'standing waves on a string'. I know that for the nth harmonic, the length of the 'string' is \frac{n\lambda}{2}. Instead of just memorizing these, I have been trying to apply my knowledge of Calculus to figure out why these numbers...

So then it would be: let -A=D M+De^(-kt)=P(t)

lol this usually happens when I do long things like this. Thanks!

Homework Statement Model for learning in the form of a differential equation: \frac{dP}{dt}= k(M-P) Where P(t) measures the performance of someone learning a skill after training time (t), M is the maximum level of performance, and k is a positive constant. Solve this differential...
